UNITED s'rATas PATENT OFFICE 'CEABLES G. TALBOTT QF STAMFORD, CONNECTICUT, ASSIGNOR TO THE BARRETT COM- PANY, A CORPORATION OF NEW JERSEY ROOFING STRIP AND PROCESS Application filed Kay 7,

This invention relates to a shingle strip or roofing element and the process of cut ting the same from a sheet of roofing material. The: strip may be cut from asheet' of manufactured roofing material that is made by saturating a so-called felt base with waterproofing material such as asphalt, applying a coating of plastic materal such as asphalt, and then covering the same with a layer of crushed stone, slatev or the like.

These sheets can be made of different widths and can be cut with very little. loss in order to make a. strip in accordance with the present invention.

One of the ob'ects of this invention is to provide a shingle strip or roofing element that will be easy to install and attractive in appearance and at the same time will afford a maximum of protection against leakage.

2 Another object is to provide a roofing element of this character that will not have the exposed portions so thin as -to present an appearance of cheapness or flimsiness.

Another object is to rovide roofing elements or shingle strips 0? different lengths and other dimensions if desired, and also to provide a thick butt or portion exposed to the weather. Another object is to provide shin le strips with tabs so constructed that no edges are exposed that will readily, absorb water. The invention will be understood from the description in connection with the accompanying drawings, in which Fig. l is a plan view of a sheet showing how the strips can be cut therefrom; Fig. 2 is a similar view showing a mod1- fied way of cutting the same;

Fig. 3 is a similar view showlng a third wa of cutting the same;

Fig. 4 is a plan view of one of the shingle strips that has been out according to Fig. 1; Fig. 5 is a section through the line aa of Fig. 4;

Fig. 6 is a plan view of one of the shingle strips cut according to Fi 2; and

Fig. 7 is a plan View 0 one of the shingle strips out according to Fig. 3.

In the' drawings reference character 1 indicates a sheet of roofing. material wide enough to form a shingle strip. This strip 1925. Serial No. 28,553.

has portions 2 cut out along one edge having parallel sides 3 and a sloping end as indicated by the lines 4. These cut out portions are spaced apart at proper distances so as to provide tabs or ortions simulating individual shingles of tlie desired width. The width of the cut out portions longitudinal of the sheet is twice the desired space between the tabs. Transverse slits 5 are cut from the pointed end or middle lines of the cut out portions 2 and terminate in longitudinal slits 6 which should be as long as the desired distances between tabs or exposed portions when the strips are laid on a roof. The length of 'the lines 5 will depend upon the desired ratio between the width of the shingle strip and the portion thereof that is to be exposed to the weather, or the amount that it is desired for one row of these shingle strips to overla a lower row. The sheet l may be severe at intervals along the lines 7 extending from one end of the slits 6 tothe edge of the sheet opposite the cut out portions 2. The distance between the lines 7 will be dependent upon how many tabs there are desired for each shingle strip.

In the modification shown in Fig. 2 in which similar lines are referred to by the same reference character followed by the subscript 2, the transverse lines 7 2 extend from the middle of the longitudinal slits 6 or in line with the slits 5 Inthis figure a modification of the cut out portions that form the tabs is also shown in the lower right hand corner in which the space 2 terminates in the straight end or square end along the line 4 as indicated.

In the modification shown in Fig. 3, the lines corresponding to those shown in Fig. 1 are marked with the same reference characters with the subscript 3. In this modification portions 2 are cut out a short distance from the edge of the sheet 1 and the lines 8 are made parallel to the edge of the sheet. Transverse slits 9 and 9 perpendicular to the edges of the sheet are cut from the lines 8 to the edge of the sheet. In this way extensions 15, 16, 17, 18, are made along the lower edges of the portions that are to be turned under (which extensions will be along 100 from this olded line to the lines6 In this way there will be a double thickness of ma- H terlal along all three sides of the space 2 when the strip is completed. By cutting the lines 9 in line. with the lines 5 and 7 extensions 15 will be provided so that the extremity thereof will be flush with the end of the strip andthe extension will extend onehalf the way across an opening 2 preferable to out the line 9 at this place at the end "of the shingle strip. It is necessary to have the extensions 15 formed in a similar way at the edges of the sheet of roofing material when the strips are cut out transversely in order to avoidlwaste of material. When so cut the abutting ends of extensions on adjacent or contiguous turned under flaps make joints half way between the edges of the spaces 2 In case it is desired to have these joints in line with one of the edges of the space 2 the slit may be out along the line 9' in line with the middle point of the beveled line 4 and the end of the line 6 so that the extension 16 will reach to the edge of the space 2 as shown in Fig. 7 when the flap is folded under, or the slit 9' may be omitted altogether so that an integral or continuous strip will exist above the upper end of the corresponding slot 2 after the portion has been folded under.

When astrip has been cut out of a sheet of roofing material as indicated in Fig. 1, the edge 8 of the sheet is folded'under along lines joining the middle points of the lines 4 to form flaps 9 (Fig. 4), and the material on each side of the slits 5 is folded to the right and left respectively to form the flaps 10. Strips 11 of waterproofing material similar to the material out of whichthe strips themselves are made may be enclosed or interposed between the main body of the strip and the flap 9 as shown in Fig. 5 when it is desired to have greater thickness of the folded portion that is to be exposed to view when the strips are laid. The flaps 9 and 10 may be cemented to the back of the sheet with any convenient cementing material such as bitumen or the like. One end of the stri shown in Fig. 4 is a straight line 12 while t e other end consists of two lines 13 and 14 offset an amount equal to the width between tabs. so that as these successive strips are assembled, all the tabs will be properly spaced apart.

In the modification shown in Figs. 2 and 6. both edges of the strip terminate in two lines 13;; and 14 offset from each other a distance equal to one-half the space between tabs so that the spaces between tabs on contiguous strips will be the proper width. Also in this modification one of the cut out portions 2 has It isroofing material as indicated in Fig. 3, the

edges or flaps are folded under along lines joining middle points of the lines 4 thus causing the extensions 15,.16, 17, 18 to provide double. thickness at the upper end of the spaces 2 The portions folded back on each side of'the line 5 will rovide double thickness along-the-edges o the space 2 so that all portions of the strip below the upper edge of the folded back portlon, as well as the three sides around the space 2 will be provided with a double thickness of'material.

Due to the fact that the'portions of the strip that are to be exposed to the weather are wholly or in part made of two thiclmesses of material, the tendency to curl after the strips are installed will be lessened and the greater thickness that is thereby provided will enhance the attractiveness of the appearance of the installation. Also, since practically all of the edges that are exposed to the weather consist of folded or bent portions of material there are no rawor cut edges exposed which might have a tendency to absorb moisture. results from cutting material of this sort and leaving the cut edges exposed to the weather.

It will be understood that these shingle strips may be cut from material different from that above described provided it is flexible or can be bent or folded back upon itself. Instead of using a sheet of roofing material of sufiicient width to cut out one row of shingle strips, the roofing sheet may be two or any other multiple times this wide so that two or more rows or strips may be cut out simultaneous] therefrom. The strips may be out either ongitudinally of the sheet of roofing material or transverse thereof. Instead of making strips with slots and tabs as described above, I may make single strips in a similar manner with the two side edges of the shingles corresponding to the ends of the shingle strips above described.

I claim:

1. A roofing element made from flexible material comprising a strip having tabs with their ends and sides folded back, some of the folded back portions of adjacent tabs being provided with extensions that abut each other when said portions are folded back.

2, A roofing element made from flexible material comprisinga strip having tabs with their ends and sides folded back upon an insert as wide as the tab and located with the outer end thereof in line with the outer end of the tab, the folded back portions and the This effect sometimes insert being cemented to the back of their respective tabs.

3. A roofing element made from flexible material comprising a'strip having tabs with their ends and sides folded back, some of the folded back portions of adjacent tabs being provided with extensions that abut each other when said portions are folded back and which are of suflicient length so that a shingle strip results having tabs, the folded back portions of which are of uniform thickness, at leasttwice the thickness of the main body portion of the strip.

4. The process of forming a composition shingle strip having reinforced tabs at one longitudinal edge thereof, which comprises cutting out openings at spaced intervals longitudinally of said strip, cutting said strip along transverse lines extending from said openings thus forming spaced tabs with extensions thereon on the front and sides of said tabs and folding back said extensions onto said tabs to reinforce the front and sides of said tabs.

5 The process of forming a composition shingle strip having reinforced rectangular tabs at one longitudinal edge thereof, which comprises cutting out notches with substantially parallel sides and sloping ends from said strip, cutting said strip along transverse lines extending from said notches, folding said strip longitudinally thereof at substantially the mid point of the sloping ends of said notches and folding the side portions of said tabs transversely of the length of said shingle strip.

6. The process of forming a composition shingle strip having reinforced tabs of greater thickness than the body portion of the shingle strip, which comprises cutting notches with substantially parallel sides and sloping ends in said strip, .slitting said strip transversely at substantially the mid point of said notches, slitting said strip longitudinally at right angles and contiguous to the first mentioned slit, folding said strip longitudinally at substantially the mid point of the sloping ends of said notches and folding the portions of the strip bounded by said slits onto said strip.-

7. The process of forming a shingle strip having reinforced tabs of greater thickness than, the body portion of the shingle strip, which comprises cutting notches with substantially parallel sides and sloping ends, the parallel side portions of the notches being of substantially twice the desired width of the space between said tabs, slitting said 0 strip transversely at substantially the mid point of said notches, slitting said strip longitudinally at right, angles and contiguous to the first mentioned slit, folding said strip longitudinally at substantially the mid point 85 of the sloping ends of said notches and folding the portion of the strip bounded by said slits onto said strip.

8. A composition shingle strip comprising a saturated felt base body portion having a plurality of tabs thereon at one longitudi- -nal edge thereof, the side and front portion of said tabs being folded back onto sai tabs, the front edges of the folded back portion of the sides of said tabs and the sides of the folded back portion of the front of said tabs being correspondingly inclined to form a continuous border about the sides and front of said tabs.

9. A composition shingle strip comprising a saturated felt base having openings with substantially parallel sides along one longitudinal edge thereof, slits extending transversely of the length of said strip from substantially the mid point of said openings to approximately the mid point of said strip and slits extending from said first mentioned slits longitudinally of said strip in both directions.

10. A shingle strip having interior openings with substantially parallel sides and sloping interior ends along one longitudinal edge thereof, slits extending transversely of the length of said stri from substantially the intersection of the s oping ends of said openings to approximately the mid point of said strip and slits extending from said first mentioned slits longitudinally of said strip in both directions, said second mentioned slits being of less extent than the width of the parallel side portions of the openings.

11. A bitumen saturated felt shingle strip comprising a body portion having'a plurality of tabs thereon, the side and front por tions of said tabs being folded back onto said tabs, the side portions being folded onto said tabs to thus provide only a double thick ness of material at the sides and front edges of the tabs.

In testimony whereof I aflix my signature.
